1.Qhov kev pheej hmoo ntawm zinc txheej yog dab tsi?
Reaction nrog Acid: Ntau yam khoom noj (xws li txiv hmab txiv ntoo, nqaij, thiab zaub) tso kua qaub los yog ya raws thaum cua sov. Zinc reacts chemically nyob rau hauv ib puag ncig acidic, tsim zinc ntsev. Cov ntsev no tuaj yeem tshem tawm thiab nkag mus rau hauv cov zaub mov.
Kev pheej hmoo ntawm Zinc Poisoning: Kev noj zinc ntau dhau tuaj yeem ua rau mob hnyav xws li xeev siab, ntuav, mob plab, thiab raws plab. Ntev - noj ntau dhau tuaj yeem ua rau muaj kev phom sij rau kev noj qab haus huv.
Zinc muaj cov ntsiab lus melting tsawg: ntawm qhov kub kom qhuav ntau dua (zoo tshaj nws qhov melting point ntawm 419 degree, uas tsis tshua muaj, tab sis hauv zos overheating tuaj yeem yog ib qho teeb meem), zinc txheej yuav tsis ruaj khov, ua kom nws tso tawm.
2. Cov cai tswj kev nyab xeeb zaub mov li cas?
Cov cai tswj kev nyab xeeb khoom noj thoob ntiaj teb (xws li Tuam Tshoj tus qauv GB, US FDA cov qauv, thiab EU's EC1935/2004) qhia meej tias cov ntaub ntawv saum npoo nyob rau hauv kev sib cuag nrog zaub mov yuav tsum tsis yog - tshuaj lom, tsis yog - adsorbent, corrosion- tiv taus, thiab tsis yog -reactive nrog zaub mov.
Ordinary galvanized steel sheets (txawm yog electro-galvanized lossis kub-dip galvanized) tsis yog zaub mov- qib ntawv pov thawj, thiab lawv cov zinc txheej thiab ib qho kab ntawm impurities xws li txhuas uas lawv yuav muaj tsis tau raws li cov kev cai no.
3.Lub sijhawm twg koj tuaj yeem "yuav" pom kev siv cov ntawv hlau galvanized?
Yog vim li cas tus nqi, qee qhov tsis yog -tus qauv lossis qis- cov khoom siv kawg yuav siv cov ntawv hlau galvanized ntawm qee qhov chaw uas tsis tuaj yeem cuam tshuam ncaj qha nrog zaub mov. Piv txwv li:
Khoom vaj tse thiab ncej
Cov cua kub ncig qhov system duct vaj tse (txawm hais tias stainless hlau yog nyiam rau cov phab ntsa hauv cov kav dej)
Cov cuab yeej txhawb nqa cov qauv
Txawm li cas los xij, thov nco ntsoov tias txawm tias cov cheeb tsam no muaj kev pheej hmoo: Yog tias cov txheej txheej galvanized dislodges vim qhov kub thiab txias, cov av noo siab, lossis cov neeg kho tshuab hnav, cov plua plav lossis oxides tuaj yeem nkag mus rau hauv cov khoom noj los ntawm huab cua ncig, ua rau muaj kab mob.
4.Dab tsi yog cov ntaub ntawv pom zoo rau cov khoom noj kom qhuav?
Khoom noj khoom haus- qib stainless hlau - Qhov no yog cov khoom siv feem ntau thiab pom zoo.
304 stainless hlau: Qhov kev xaiv ntau tshaj plaws, muab kev tiv thaiv corrosion zoo heev thiab cov khoom siv kho tshuab, thiab yooj yim los ntxuav thiab tua kab mob.
316 stainless hlau: Muaj kev tiv thaiv zoo dua rau cov tshuaj chloride corrosion dua 304 thiab pom zoo siv rau hauv ib puag ncig uas muaj ntsev ntau lossis av noo.
Cov hlau tsis muaj hlau no muaj qhov chaw du, tsis yog - tshuaj lom, tshav kub- tiv taus, thiab tsis yog -reactive nrog zaub mov, ua raws li cov qauv kev nyab xeeb khoom noj.
Khoom noj khoom haus- qib aluminium alloys
Kev kho anodic oxidation feem ntau yuav tsum tau ua ib qho nyuaj, ruaj khov, tsis yog - oxide oxide zaj duab xis uas zoo tiv thaiv cov txhuas los ntawm kev sib cuag cov khoom noj. Xyuas kom meej tias nws yog "zaub mov-qib anodizing."
Khoom noj khoom haus- qib txheej txheej
Siv cov zaub mov muaj ntawv pov thawj-qib, siab-kub- tiv taus txheej rau carbon steel substrate. Cov txheej txheej no yuav tsum ruaj khov kom ntseeg tau tias nws tsis decompose los yog tso tawm cov khoom tsis zoo ntawm qhov kub thiab txias ntawm cov khoom siv.
5.Cov ntsiab cai tseem ceeb yog dab tsi?
Tsis txhob siv cov coils zoo tib yam galvanized nyob rau hauv txhua qhov chaw uas tuaj yeem cuam tshuam ncaj qha lossis tsis ncaj qha rau cov zaub mov.
